Abstract: A cable reel handler for mounting at the rear of a truck for loading and unloading of cable reels. The handler comprises a pair of lift cylinders pivotally supported in fined positions on the track, a pair of lift arms pivotally connected to the track rearwardly of the lift cylinders, and a piston and cylinder arrangement for moving the lift arms transversely whereby the spacing between the lift arms can be varied so that cable reels of different sizes can be engaged by the lift arms. A pivoting link is connected at one end to each one of the lift cylinder pistons, and each link is connected at its opposite end to one of the lift arms. The connections at each of the ends of the pivoting links comprise swivel connections whereby the loading and unloading can take place at any variation of the spacing between the lift arms. The piston and cylinder connection between the lift arms permits independent movement of the lift arms. A separate telescopic column with a ratchet and pawl mechanism extends between the lift arms to provide an interlock preventing inadvertent separation of the arms when a cable reel is attached.

Abstract: For the electrically isolated transmission of digital signals, an isolating path (IP) of the channel formed by means of a transformer is used. The channel further comprises a conversion stage (SC1) for converting the digital signal (txd1) to a transmissible coupling signal (txt1) and a conversion stage (SC2) for converting a coupling signal (rxt2) to the digital signal (rxd2). This conversion is accomplished by means of a monostable multivibrator. The coupling signal (txt1) is a square-wave voltage (AU2) which is generated by means of a delay circuit (4) in the conversion stage (SC1) and is converted on the isolating path (IP) to a square-wave voltage (AU3) serving as the coupling signal (rxt2). Furthermore, the direction of transmission is switchable in operation by means of activatable digital-signal ports (TXD1', RXD2', TXD2', RXD1') of the channel. The activation is effected by means of selection signals (rxa1', rxa2'). When no signal is being transmitted, the channel is in a defined initial state. The channel has low power consumption and the transmitted signal is highly immune to electromagnetic interference.

Granted: 2009-10-20
Abstract: An element for use in ultrafiltration or microfiltration of potable water has a large number of small diameter hollow fibre membranes attached in a slightly slackened state between two headers but in fluid communication with only one of the headers. Side plates attached to the sides of the headers define vertical flow channels containing the membranes. The headers, membranes, side panels and T connectors define membrane elements which may be placed side by side with other elements to create membrane modules which can be stacked on top of each other to form membrane cassettes of various sizes having continuous vertical flow channels through the entire cassette. To pot the fibres, a suitable number of fibres are gathered in a bundle and dipped in a pool of liquid wax which freezes seconds after the bundle of fibres are removed. The waxed fibre bundle is then inserted into a recess in a header. Potting resin is poured into the header to cover the fibre bundle to a depth greater than the distance that the wax wicked up the fibres. The wax is melted out of the header. The membrane modules or cassettes are arranged in an open tank to cover a substantial part of the cross sectional area of the tank, preferably 80% or more. In first and second processes, tank water flows upwards and downwards through the flow channels respectively.
